Use Window Film To Prevent Bird Collisions

Posted on
It’s always sad when a bird dies colliding with a clear glass window. This tends to happen fairly often in urban areas and has been known to occur at people’s homes as well, especially during the Spring and Autumn migrations. No one knows exactly how many birds are killed this way, but annual U.S. estimates are in the hundreds of millions.

When designed according to the 2 x 4 rule, (see boxed out text) patterned films can be effective at preventing bird collisions. While they interrupt reflection for the birds, they can also create interest and preserve a degree of visibility for humans. patterned window filmResearchers are testing the effectiveness of different pattern densities, configurations, and colors. One thing we know for sure: patterns applied to the inside surface of double-paned windows won’t be effective if not bold enough overcome reflections of the outer window pane.

Branded Graphics

If designed densely enough, custom window graphics used for branding and street activity can conveniently bring marketing and bird-friendliness together. The gear graphic here is paired with a frosted film for added privacy, which will definitely obscure any reflections. If more gears were used, they alone could custom window graphicsdistort the glass enough to deter birds from striking the window.

Frosting/Etching and Other Treatments

Making your windows completely opaque by applying a film that mimics etched, stained, or frosted glass is an excellent way to reduce or eliminate bird collisions. Rather than replacing your windows with expensive specialty glass, installing a film will be a much simpler solution and save you thousands of dollars.

lumisty window film

A new line of film we suggest for you in is called Lumisty. At certain angles from the outside, lumisty makes your windows look opaque (deterring the birds), while from the inside your view remains clear. This is a great option if you have a high-rise view you don’t want to obstruct.
